What should I do if acne turns into a hypertrophic scar or keloid?

1. For smaller keloids, topical medications such as tretinoin cream or asiaticoside cream can be applied to help fade the scar and improve symptoms. 2. Under medical supervision, injections of medications such as bleomycin hydrochloride or fluorouracil may be administered to exert anti-inflammatory effects and aid in treating hypertrophic scars. 3. Laser therapy utilizes photothermal effects to stimulate collagen production in the skin, helping restore a smooth skin surface. 4. For severe cases of scar hypertrophy, surgical excision may be considered.
